Port of Spain: Ending months of complex negotiations, India and Canada Saturday announced here the conclusion of a civil nuclear deal that will enable New Delhi to access Canadian nuclear technology and uranium after a gap of 34 years.

The breakthrough was announced after Prime Minister Manmohan Singh held talks with his Canadian counterpart Stephen Harper on the sidelines of the Commonwealth Heads of Government Meeting (CHOGM) here.

"We have now got an agreement which means this is a tremendous opportunity for both countries," Harper said here while underlining that it was "a tremendous step forward" in bilateral relations.

"Canada is a supplier, obviously an integrated supplier in the nuclear energy field and India is an expanding economy that has great energy needs," Harper said.

The nuclear agreement promises to transform bilateral relations that turned frosty when Ottawa cut off atomic trade after New Delhi's 1974 nuclear test and accused the latter of misappropriating Canadian reactor designs in the test.

Harper, however, added that it will take "a little time to complete the normal legal text and the ratification process."

Lauding Harper for giving a political push to the negotiations, Manmohan Singh said: "This is a tribute to the prime minister's great leadership and the way the civil service functions in Canada."

"It augurs extremely well for the development of our relations," he added.

The deal is likely to be signed when Manmohan Singh goes to Canada to attend the G20 summit in June next year where he will also hold bilateral talks with the Canadian leader on the sidelines.

After this deal is inked, Canada will become the seventh country with which India has struck civil nuclear pacts since the Nuclear Suppliers Group (NSG) allowed India to resume global nuclear trade in September 2008.
